Are Molar Mass and Molecular Mass the same thing? If they are different, then why are they used interchangeably?
exis [7]

At this point there are two answers:  one says that there is no difference, except for the units;  the molecular weight (MW) is the mass of one molecule, while a molar mass is the mass of a mole (6.02 x 10 ^ 23) of molecules.

While in certain contexts both statements can be shown to be true, I'm not sure these answers really provide you with the insight you're looking for.

So, we'll look at your question from a different perspective.   Take a real example, something simple like water.  Water has a nominal MW of 18 (so we'll use nominal precision for simplicity, instead of the 4-places often used for these types of calculations).

The MW of water (formula = H2O) is the weight of one atom of oxygen, which = 16 amu [8-neutrons at 1 amu each plus 8 protons at 1 amu each = 16 amu), plus two atoms of hydrogen, at 1 proton (1 amu) each.  Normal everyday hydrogen has no neutrons.  So for H2O, we have a total molecular weight of 18 amu.

From the CRC reference book we find that one amu weighs 1.66 x 10 ^--24 grams.  Multiplying the two and in keeping with the two units of precision we're working with, one molecule of water has a mass of  29.8 x 10^-24g, or [3.0 x 10 ^ -23 g] per molecule of water.

A Mole is simply Avagadro's number (6.02 x 10 ^ 23) of anything... protons, baseballs, whatever.  The term Molar Mass in chemistry refers to the mass of a mole of molecules.  So in this case a molar mass of water molecules is Avagadro's number of them, the mass therefore being [6.02 x 10 ^ 23] x 3.0 x 10 ^ -23 g/ molecule] =  18.0 g

Summarizing:

Molecular Weight is the weight given in amu of an atom or molecule.  For H2O, the MW is 18 amu or 3.0 x 10 ^ -23 g.

Molar Weight is the weight, usually in grams of 6.02 x 10 ^ 23 measurements which happens to be equal to the MW of the molecule (or atomic wt. of the atom) , and for water is 18.0 g.

So, while MW and molar weight are related, their absolute values are magnitudes apart.

what would be the effect on the melting point of a sample if it were not dried completely after filtering the recrystallized sam
jok3333 [9.3K]

The melting point of the sample if it is not dried completely after filtering the recrystallized product will have a broad range and will occur at lower range than the actual value.

What is melting point?

Melting point is the temperature at which the solid form of a given substance changes to the liquid form at atmospheric pressure. It is important because, by using the physical property of a substance the substance can be identified.

The sharp range melting point of the substance indicates the purity of the substance. If the sample is not dried completely after recrystallisation, the melting point will have a broad range.

Therefore, if the sample given is not dried completely, it will be impure and the decreases the melting point of the substance. So the actual melting point of the substance cannot be determined.

You have 47.0 mL of a 2.00 M concentrated or "stock" solution that must be diluted to 0.500 M. How much water should you add?
Inessa [10]

The required volume of water to make the dilute solution of 0.5 M is 188 mL.

<h3>How do we calculate the required volume?</h3>

Required volume of water to dilute the stock solution will be calculated by using the below equation as:

M₁V₁ = M₂V₂, where

  • M₁ & V₁ are the molarity and volume of stock solution.
  • M₂ & V₂ are the molarity and volume of dilute solution.

On putting values from the question to the above equation, we get

V₂ = (2)(47) / (0.5) = 188mL

Hence required volume of water is 188 mL.

The pressure inside a gas cylinder is 3,506 mmHg ,how many atmospheres of pressure is the gas exerting on the cylinder
slavikrds [6]
Converting between atmospheres and millimeters of mercury. One atm. equals 760.0 mm Hg, so there will be a multiplication or division based on the direction of the change. Solution: multiply the atm value by 760.0 mmHg / atm.
answer=
3506 \div 760 = 4.6746 \: atm
